A brief introduction:
HCB seriesCage type valve seatAn improved pressure balanced valve sealing ring, the valve sleeve is equipped with high-performance, effectively improve the level of leakage, valve fluid channel was streamlined S, also has an improvement in the steady flow of fluid around the sleeve guide wing, has the advantages of small pressure drop loss, large flow rate, wide adjustable range the flow characteristic curve, high precision, good dynamic stability, low noise, small cavitation corrosion.The valve is equipped with multi spring diaphragm actuator, compact structure, large output force.
